IMPROVEMENT IN SHAKERS FOR TH RESHING MACHINES.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern Be it known that I, Mosns A. KELLER, ofLittlestown, in the county of Adams, and State of Pennsylvania, haveinvented a new-and useful Improvement Ll-ll Shakers forThreshing-Machines; and Ido hereby declare that the following is a full,clear, and exactde- "scription thereof, which will enable others skilledin the art to make and use the same, reference being had totheaccoinpanying drawing, formin g part of this specification, in which-Figure 1 is a vertical longitudinal section of my improved shaker, takenthrough the line a: x, fig. 2',showing it attached to thedischarge-spout of a thresher.

Figure 2 is a top or plan view of the same.

Figure 3 is a detail cross-section of one of the shaking-bars.

'A is the frame of the shaker, the forward-end of.

which is detachably secured to the discharge-spout of atlu'eshing-machine.

The rear end of the frame Ais supported upon a frame, B, the upper endof which is adjustably pivoted to the rear part of the said frame A, sothat the rear end of the shaker may be raised or lowered, as required.

The bottom a, of the shaker A, may bein the form of a perforated plate,or of a screen, as may be desired.

In the bottom a, near its rear end, is formed an opening, 0, which iscrossed by bars 1) running longitudinally with the shaker A, to insurethe grain being entirely removed from the straw, before the said strawescapes from the shaker.

g E isa bar runninglongitudinally through the middle part of the shaker,and securely attached to the bottom a. The upper edge of the barn;notched, 0r

formed into a series of inclines, as shown in fig. 1, so as toconstantly tend to raise the straw from the bottom of the shaker as itis passing back through said shaker.

F are four bars running longitudinally through the shaker, the ends ofwhich are pivoted to cranks formed upon the shafts G, which work inbearings in the sides ofthe shaker A.

Each of the cranks of the shaft G, projects at a diliere'nt angle fromthe other, so that the bars F may be raised and lowered alternately.

j are short cross-bars attached at right angles to the bars F. a

The bars F and cross bars f, are provided with teeth projecting downwardand rearward, soas, as the bars h f move downward and strike against thestraw moving through the shaker, to kn ock the kernels of grain out ofsaid straw, and at the same time to move the straw toward the rear endof the shaker.

The four crank-shafts are driven from the thresh- 1. The bars F, hungupon the crank-shafts G, and j carrying the short cross-bars anddownwardly-projecting teeth, when provided with the books I, projectinginto the discharge-spout of the thresher, for the purpose of guiding thestraw to the shaker, as herein shown and described.

2. The opening 0 and bars D, arranged and op erating in connection withthe bottom of the shaker, substantially as herein shown and described,and for the purpose set forth.
